Notes:
On the Addition of Alkyldichloroboranes to Bis(η5-cyclopentadienyl)dihydridotungstenReaction of basic [Cp2WH2] (1) with the Lewis acids iPrBCl2 and tBuBCl2 does not lead to adducts of the type [Cp2WH2 (RBCl2)] [R = iPr, tBu]. The zwitterions [CpWH3(η5-C5H4BRCl2)] (R = iPr, 2a; tBu, 2b) having an exocyclic boron substituent were isolated instead in 60% yield. The molecular structure of 2b crystallizing in the space group P21/n is proved by X-ray structure determination.
